Actually...

Douglas Bader was shot down in August of 1941. It was a bad month because within a week of one another, they also lost Eric Lock.

On the subject of DB, while he was a great man in many respects, I do find it odd that his name is so synonymous with the Battle of Britain when so many others had higher scores and were frankly better pilots. Sheer personality says it all I suppose. 'Sawn-Off' Lockie was the leading British ace of the battle (and in my opinion the leading ace of the battle period) and few know who he is. In my humble opinion Bader shouldn't have been allowed to play any part in the 'Big Wing' controversy given his rank, and it's always been said he played a part in the national shame of dumping Dowding and Parks. Leigh-Mallory was something of an ass-hat from what I've heard and read.
